Question

What is the value of the expression 8−2 ? 64 116 164 −16

Answer 1

Any number to the power of a negative integer will be 1 over that number with the absolute value of the power, so it looks like this:

$x^{-2} = \frac{-1}{x^{2}}$

Therefore, you just need to 8² which is 64, and then do 1 over that (1/64) because it's a negative power.
